The right atrium is one of the four chambers of the human heart, located on the right side. It receives deoxygenated blood from the body through the superior and inferior vena cava and then contracts to pump the blood into the right ventricle for further circulation. It plays a crucial role in the cardiovascular system by facilitating the flow of blood and ensuring efficient oxygenation throughout the body.
